If you can get your hand on the radiator core...the palm of your hand... you can feel around it (carefully) to see if there are zones that are cooler than others. If there are, the cool areas are where water/coolant is not getting through (and thus is not heating up the core) and this means there is an internal clog in that area. Sometimes you can fix this with some of the radiator cleaning stuff you can find on the shelf at an auto parts store. Often, however, it won't work and you'll have wasted several hours of time and...possibly, because this stuff is pretty caustic and has to be properly neutralized, you could damage the raditor. If the cool areas are many or as large as your hand, start looking for a rediator repair shop.
